Polar stratospheric clouds facilitate the formation of

Options

  1. AClONO 2
  2. BHOCl
  3. CClO
  4. DCH 4

Correct answer

B. HOCl

Step-by-step solution

Polar stratospheric clouds surface act on catalyst which provided surface on which hydrolysis of ClONO 2 takes place to form HOCl (Hypochlorous acid) ClONO 2 g + H 2 O g → HOCl g + HNO 3 g Polar stratospheric clouds (PSCs) play a central role in the formation of the ozone hole in the Antarctic and Arctic.
